SPECIFICATION forming part of Letters Patent No. 224,286, dated February 10, 1880. Q

' Application filed July 10, 1878. I

To all whom it may concern: V

7 Be it known that I, AUGUST GERARD, of Soignies, Belgium, (a subject of the King of Belgium,) have invented an Improvement in Machine for Shaving and Fleshing Hides and v Skins, of which the following description, taken .of said cylinder.

in connection with the accompanying plate of drawings, hereinafter referred to, forms a full and exact specification, wherein are set forth the nature and principles of theinventi'on, by

which the same may be distinguished from' others of a similar class, together with such parts thereof as are claimed as new and are desired to be securedby Letters Patent of the United States.

The nature of this invention consists in providing the machine with a pressure-cylinder, in connection with knives arranged obliquely to each other upon a main or forward shavingcylinder, with their ends meeting in the center By such arrangement of the knives the hides are stretched simultaneously with the shavingoff of the hair from the hides, said shaving and stretching being accomplished effectually and with great rapidity.

In the accompanying drawings, Figure 1 is a front elevation, and Fig. 2 a side elevation of the same.

The same letters of reference ,denote like parts in the several figures.

' a a is the framing, solidly bolted together and bolted to the floor. Upon this framing is supported a cylinder, b, to which are attached the hides by hooks c. a

d is a counter pressurecylinder, which is covered with a thick coating of caoutchouc or other elastic body, in order to yield to the asperities that may present themselves in the hide.

e is a shaving-cylinder, provided with two series of helic'oidal blades, f, so arrangedwith relation to each other that the ends of each blade will terminate in the center of the cylinder. They are mounted, as shown, obliquely with the cylinder, and their edges are blunt for shaving the hair off; but when treating the inside of the skin, or fleshing it, I replace this cylinder by one on which the blades are mounted in a similar manner, and their edges are made sharp in order to scrape off all fatty or greasy matter. The position of the blades, as described, in relation to each other has the effect to stretch out the hide during the shaving or fleshing operation on the whole surface.

On theshaft g of the cylinder 6 is mounted a pinion, h, gearing in a wheel, 2', on the drivingshaft j, and the blocks or bearings in which turns the cylinder 0 are so formed as to terminate in two racks, 7c is, which are worked by two toothed segments, Z l, set in motion by means of the levers m and m, which put the pinion h in or out of gear, pushing the eylin der 0 to or from the counter pressure-cylinder d at will. On the other extremity of the shaft j is 'der b, with which it is'put in and out of gear by means of the handle or lever w. y

:20 is a pipe placed vertically over the machine, andpierced with holes, through which pass jets of water onto the hide during the operation of shaving or fleshing. To the machine is also attached, by means of an elbowlever, a treadle, y, for the purpose of allowing a bar secured to the frame to engage with the lever m.

The working of the machine is as follows The lever m being thrown back, the cylinder 6 is out of gear and removed from the counter pressure-cylinder d, and the handle w being turned to the left of the operator, the cylinder b is liberated, and can be turned by hand, so as to be able to easily fix the hide on the hooks c, and this is done in such a manner that just one half of the same is presented to the action of the blades f, while the otherhalf remains hangingloose infront of the operator. The handle w is then turned to the right and the lever mbrought forward. The blades f come in contact with the hide, from which, on account of their rapid rotation, they remove the hair almost instantaneously. The operator then throws the machine again out of gear, and, releversmm, cylinder 1), having hook c, and pipe 10 moving the hide from the hooks, replaces it at, substantially as shown and described.

again in the reverse position, so that the seo- In testimony that I claim the foregoing I 0nd half is operated on in the same manner. have hereunto set my hand this 8th day of Having thus described my invention, what February, 1878.
